The aim of this paper is to suppress negative effect of noise on complex firing patterns of neurons and extract deterministic dynamical relationship underlying irregular interspike intervals. We first give a brief introduction to ISI data to be analyzed. Then a simple nonlinear noise reduction method based on chaos theory is presented. The method is finally used to analyze ISI data both from a theoretical model and experiments.

Essay 2: This paper examines the effect of obesity on earnings. It analyzes the 2001 National Health Interview Survey of Taiwan using the ordered probit model with sample selection in which earnings are defined as an ordered variable. We also transform the earnings from ordered variable to continuous variable and use the Heckman's two-stage model to estimate the effect.
第二篇:本文主要在探讨肥胖对收入的影响,并使用国家卫生研究院,民国90年国民健康访问调查资料(National Health Interview Survey, NHIS)来进行分析,并采两阶段的ordered probit with sample selection模型来进行估计,其中第一阶段为样本的就业选择问题,而第二阶段为样本在有就业的情况下,肥胖对劳动者收入的影响,而此收入为区间资料;另外,本文还将收入的区间资料转换为连续资料,以Heckman's two-stage的方法估计,并比较两估计结果。

Cooperating the advantages of SVM solve classification problems about small sample set, non-linear and multi-dimension model identification, I use SVM to train the sample set of different frequency signal and look for a super plane to divide the data into two parts. This method gets rid of complex computation which is a flaw of traditional decoding method.This paper introduces the theory and algorithm of SVM at first. It proposes to use the SVM to decode FSK signal based on the classifiable character of SVM.
